[Discrimination of the soil yeast species Williopsis saturnus and Williopsis suaveolens by the polymerase chain reaction using nonspecific primers].

Thirty-five yeast strains of the genus Williopsis, analyzed by the polymerase chain reaction with the universal primer N21, were found to belong to two sibling species, W. saturnus and W. suaveolens. Such affiliation of the strains studied agrees well with the results of genetic and physiological investigations.
